[A REVISAR] Troldtekt design acoustic panels: creativity, comfort and sustainability in a single material

In contemporary architecture, materials are no longer chosen solely for their functionality. They must also contribute to the visual language of the space, improve the wellbeing of the people who use it and respond to increasingly demanding environmental requirements. Troldtekt® design acoustic panels are an example of how these three requirements can come together in a single product.

Designed and manufactured in Denmark, and distributed exclusively by THU in Spain, Troldtekt® panels allow architects and interior designers to create expressive, technically advanced surfaces that are aligned with responsible construction.

Beyond the acoustic panel: design conceived at surface scale

One of the keys to Troldtekt® Design wood wool acoustic panels is their ability to create continuous, customised surfaces. Thanks to their system of invisible overlaps and grooves, the panels can be installed without visible joints, creating clean, dynamic and aesthetically coherent compositions. They can also be rotated 90°, which further broadens the possibilities for visual play with pattern, rhythm and orientation.

These acoustic panels are not conceived as isolated pieces, but as part of a whole that can extend across ceilings and walls, acting as an “architectural skin” that gives the project its character.

12 families, 18 patterns, endless combinations

The Troldtekt® Design range comprises 18 different patterns grouped into 12 families, each with its own visual language, yet all compatible with one another. This versatility makes it possible to combine designs within the same surface without disrupting either the aesthetic harmony or the acoustic performance.

1. Troldtekt® Line Design

Fine parallel grooves for an elegant, understated rhythm. Ideal for offices, auditoriums or reception areas seeking a modern, restrained finish.

2. Troldtekt® Line (Custom Length)

A customisable version of the previous design, in which the length of the grooves can be adjusted. It gives greater control over the final visual effect.

3. Troldtekt® V-Line 1way / 2way

V-shaped grooves that create directional or grid-like effects.

4. Troldtekt® Curves

Gentle undulations. Ideal for spaces with an organic character or for breaking the rigidity of rectilinear compositions.

5. Troldtekt® Puzzle

Panels that fit together like the pieces of a jigsaw puzzle. Particularly suitable for communal areas, libraries or educational settings where a playful or creative effect is sought.

6. Troldtekt® Rhomb

Interconnected rhombuses that bring dynamism and a very attractive visual effect to large surfaces.

7. Troldtekt® Tiles

A design that simulates the appearance of tiles within the same panel. Useful for creating a sense of order and modularity without visible joints.

8. Troldtekt® Star

A motif reminiscent of a star or geometric flower, with a repeating central pattern. Ideal for ceilings in foyers, auditoriums or highly visible spaces.

9. Troldtekt® Grid

A classic grid offering restraint and symmetry. Highly effective in institutional or corporate spaces seeking sobriety and visual precision.

10. Troldtekt® Dot

Small perforations distributed randomly or in a controlled pattern. It adds texture without sacrificing a minimalist character.

11. Troldtekt® 3D

Genuine volume, ideal for creating plays of light and shadow.

12. Troldtekt® Wave

One of the most sculptural options: panels with three-dimensional waves reminiscent of the movement of water.

Complete freedom of colour: the full RAL and NCS ranges

Troldtekt design acoustic panels can be manufactured in any colour from the RAL chart. This allows them to blend harmoniously with the overall palette of the project or, conversely, to create deliberate contrasts that highlight particular areas.

The paint used is water-based. It also preserves the natural texture of the visible wood wool, which reinforces the material character of the product and avoids flat or artificial-looking finishes.

Maximum acoustic performance: up to αw = 0.90

Troldtekt® panels combine wood wool and cement, which gives them a high sound absorption capacity, particularly at medium and high frequencies. Depending on the mounting configuration, they can achieve values of up to αw = 0.90, making them an ideal solution for spaces where speech intelligibility and acoustic comfort are essential.
Because they are integrated directly into ceilings or walls, these panels remove the need to add secondary acoustic elements. The construction system is simplified and the result is a cleaner, more functional and visually coherent environment.

A material that looks after the interior: comfort and health

Troldtekt acoustic panels also help to improve the indoor climate. Their composition allows air to pass through, helping to maintain a healthy relative humidity in enclosed spaces. This reduces the risk of mould, prevents overly dry environments and promotes better air quality.

The products are certified with labels such as Blue Angel and M1, which guarantee low emissions of harmful substances. This makes them a safe panel for sensitive interiors such as hospitals or nurseries. They are hypoallergenic, contain no hazardous volatile compounds and require very little maintenance: a damp cloth or a vacuum cleaner with a brush attachment is all that is needed to keep them looking as good as new.

Commitment to sustainability

One of the most innovative aspects of Troldtekt® Design is the option of including FUTURECEM™ in its formulation, a type of cement developed in Denmark that reduces CO₂ emissions by 30 % during manufacture compared with traditional cement. Furthermore, thanks to its natural carbonation process, it is able to absorb more carbon than it generates over its service life.

The wood used is FSC or PEFC certified and comes from sustainably managed forests, and the entire manufacturing process takes place in facilities powered mainly by renewable energy.

These credentials have enabled Troldtekt® panels to obtain certifications such as:

• Cradle to Cradle™ Gold

This makes them an ideal choice for projects seeking LEED, BREEAM or other international sustainable building certifications.

International recognition

The excellence of Troldtekt® Design has been recognised by some of the most prestigious design awards in the industry. These include:
• German Design Award
• ICONIC Award (Innovative Interior)
These awards underline the value of a solution that combines technical precision, contemporary aesthetics and respect for the environment.

Real applications: from Oracle to educational spaces

Thanks to their versatility, Troldtekt® panels can be adapted to all kinds of spaces, such as:
• Educational centres: where acoustics are key to understanding.
• Offices: to encourage concentration and wellbeing.
• Museums or galleries: where design and comfort go hand in hand.
• Hotels and restaurants: where a carefully crafted sensory experience is sought.
• Sports facilities and swimming pools: thanks to their impact resistance (DIN 18032) and their moisture resistance classification (Class D, 98%).
